Municipal waste facilities, pallet and sawmill operations, and compost contractors alike will appreciate the cost of operation-minded qualities of the all new HG4000 horizontal grinder. Among them is the 445 hp (332 kW) Tier 4i (Stage IIIB) Iveco diesel power plant that has shown considerable fuel savings over similarly powered engines in this application.

Features and Benefits

  • Meets owner towing preferences with a European-specific pintle hitch and center axle trailer that complies with European Union road regulations
  • Enhances fuel efficiency and helps extend component wear life with adjust-on-the-fly feed roller downforce which can set as optimal for the incoming material.
  • Improves infeed traction for productive material entry into the mill with a crush boost feature that momentarily enables increased feed roller downforce.
  • Maximizes engine power diverted to material processing functions and reduces sound level with an electrically powered cooling fan array.
  • Increases processing efficiency with hinged, dual screens designed to maximize screen area surrounding the drum. Screens are interchangeable and reversible for flexibility in desired end-product and exceptional wear life.
